monthly instant output leads to failure.

[whannah1]

For some recent ne256 runs on Perlmutter I accidentally used Averaging Type: Instant for my monthly output stream and it led to this error message:

 800:

This is related to #2662 and PR #2664. I can't imagine why anyone would want monthly instantaneous output - but it seems weird for the model to fail in this manner for these settings.
